LOCKER FITTING.

Application filed June 22,

T 0 all whom it may concern Be it known that I, Ln ROY A. WVILKIN- SON, a citizen of the United States, residing at .aurora, in the county of Kane and State of Illinois, have invented a certain new and useful Improvement in Locker Fittings, of which the following is a specification.

My invention relates to locker fittings, and more particularly to a locking plate and mounting therefor. The object of the invention is to provide a simple fitting which will permit the locking plate to rotate freely and will at the same time afford great strength and a high degree of protection against forcible entry.

I obtain this object by the construction shown in the accompanying drawings in which- Figure 1 is an assembly view in perspective shown from the inside of the door.

Figure 2 is a vertical, axial section, and

Figure 3 is a distributive view illustrating the relationship of the various parts.

Like numerals denote like parts throughout the several views.

The locker door 1 is, in the illustrated form, of sheet metal and has a circular hole 2 into which the head 3 of the locking plate fits loosely. This locking plate has a neck 4 which connects the head 3 to the body 6. In the form shown the locking plate has a hole 7 passing through it for receiving the shank of the door knob (not shown) or other means by which the plate maybe rotated. A mounting plate 10 is secured to the inside of the door, usually by spot welding. It is formed in two parts, as best shown in Figure 3, being separated along a straight line 11, and the parts having notches 12 which accommodate the neck of the locking plate. When assembled, the mounting plate intervenes between the body of the looking plate and the back of the door and enters into the neck of the locking plate, thus holding it most securely and at the same time permitting it to freely rotate. Ordinarily, the head is thicker than the metal of the door and hence projects in front of it, thus affording means by which the operator may grasp the locking plate under certain conditions. Usually, however, the rotation is effected by means of the shank of a door knob, as above mentioned. The head of the locking plate fills the opening in the door and thus prevents the entry ofa tool of any 1921. Serial No 479,504.

size, but immediately behind the opening is the mounting plate which presents a blank surface and consequently prevents the insertion of a jimmy or prying tool. Even if the metal of the door, surrounding the head, were pried outward, the locking plate could not be dismounted, for the mounting plate covers a large area of the door and forms a complete shield for preventing access to the body of the locking plate. In every respect, therefore, the construction is rigid and proof against unauthorized entry.

The mechanism operated by the locking plate is not an essential part of the present invention. To illustrate the purpose of the locking plate, however, I have shown fragments of locking bars 15, 16 pivoted to the locking plate on the inside of the door.

on desired, the locking locked against rotation by means of a fiat key lock 20 having a bolt 21 adapted to project into a notch 22 formed in the edge of the locking plate as best shown in Figures 1 plate may be vents the locking plate from being rotated in a direction to retract the locking bars 15, 16.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a locker, the combination of a sheet metal door having an aperture extending through it, a rotatable locking plate having an annular neck and a head projecting through the aperture in the door, and a flat, multi-part collar secured flatwise against the inside of the door and entering the neck of the locking plate for rotatably mounting the latter upon the door.

2. In a locker, the combination of a sheet metal door having a circular hole in it, a locking plate having a head adapted to loosely fit the hole in the door, the plate having a neck separating the head from the body of the plate, and a mounting plate secured to the door and adapted to lie between the door and the body of the locking plate, and adapted to enter the neck of the locking plate for securely holding the same journaled upon the door.

3. In a locker, the combination of a sheet metal door having a hole in it, a locking plate having a body portion, a head portion, and a neck of reduced diameters joining the head and the body portions, and a mounting plate formed in two parts "fastened to the inner surface of the door and adapted to enter the neck of the looking plate for holding it journaled upon the door, the two parts of the mounting plate meeting upon a line, and being notched to accommodate the neck portion of the locking plate.

4. In a locker the combination of a sheet metal door having an orifice, a rotatable locking plate on the inside of the door having an annular neck and a head projecting through the orifice, a multi-part collar fastened to the inside of the door and entering the neck of the locking plate for rotatably mounting the latter upon the door, and a bolt type lock also mounted upon the door and having a bolt adapted to move into and out of engagement with the locking plate for locking and releasing the latter.

5. In a locker, the combination of a sheet metal door having an orifice locking bars on the inside of the door, a rotatable look ing plate on the inside of the door connectedto said bars for operating them, the locking plate having an annular neck and a head projecting through the orifice, a multipart collar fastened to the inside of the door and entering the neck of the looking plate for rotatably mounting the latter upon the door, and a bolt-type look also mounted upon the door and having a bolt on the inside of the door adapted to move into and out of engagement with the locking plate for locking and releasing the latter.

In Witness whereof I have hereunto subscribed my name.

LE ROY A. WILKINSON.
